Well, this weekend I took a waterproof bandaid, cut the bandage part out, and put one end each of the band aid on my nipples horizontally. I also pulled the hair back from my nip and made sure to put that sucker on the skin. I ran 26 miles Saturday. I think that sucker almost pulled my nip off when I went to take it off. It would NEVER have come off. This is simple, cheap and very effective. I will use this from now on. Thanks all.

If you get some athletic tape or waterproof medical tape, you can tear off a tiny little 1 cm x 1 cm piece that only covers the tip of the nipple and only sticks to the non-hairy areola. Simple, cheap as dirt, and works extremely well in my experience.
